I hope this isn't spoiling anything, but the key to this solution, starting from the "stuck" screen shot, is found in a very recent post on this subject.

The symmetry of the open spaces in this puzzle is scary. This is what it looks like if an X was misplaced or a clue was misinterpreted. All those open rectangles beg you to hit the reset button or start trying some of the limited choices that remain to see if you can find a conflict quickly.

The two remaining clues and other available information are all that is needed to solve this with pure logic.
